Increasing RCD senstivity

Increasing RCD senstivity

Increasing RCD senstivity

(OP)
I got a couple of fixed 300 mA miniature RCCB and wonder if there is a way to increase its sensitivity to anything near 30 mA.
The first think is to installed a capacitor to neutral across it but is there a way to alter the internal circuit?

1. STOP, STOP, STOP ! Do NOT tamper with the calibration, trying to change it from 300mA to 30mA.
2. FYI: (30mA) is for [life saving], strongly accepted in the IEC world. 300mA is for other purposes.
3. You should NOT attempt to tamper with it!. (Replace them) with [30mA ]. Stop.
